[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 , Figure 3As shown, the combined blade comprises a blade body, the blade body is provided with an axial hole, and is characterized in that the blade body is composed of a main blade body 1, an upper blade body 2 and a lower blade body 3, and the main blade body 1, the upper blade body 2 and the lower blade body 3 are all provided with a plurality of blade bodies 4 for processing workpieces, the main blade body 1 is provided with a fixing portion 5 for installing the upper blade body 2 and the lower blade body 3, the fixing portion 5 is provided with a positioning rod 6 for positioning the upper blade body 2 and the lower blade body 3, the upper blade body 2 and the lower blade body 3 are both provided with a through hole for the positioning rod 6 to penetrate, and the positioning rod 6 is provided with a A positioning assembly 7 for positioning the upper blade body 2 and the lower blade body 3 is provided, and the positioning assembly 7 is composed of a positioning portion 8 and a connecting spring 9. A mounting groove 10 for installing the positioning assembly 7 is provided on the positioning rod 6. One end of the positioning portion 8 extends into the mounting groove 10 and is connected to the connecting spring 9, and the other end of the positioning portion 8 extends out of the mounting groove 10 and abuts against the upper end of the upper blade body 2 or the lower end of the lower blade body 3. Under the action of the connecting spring 9, the positioning portion 8 is extended and retracted in the mounting groove 10, so that the upper blade body 2 or the lower blade body 3 is fixed to the main blade body 1.

[0016] To explain in further detail, when the upper blade body 2 needs to be installed, pressure is applied to the positioning portion 8 of the positioning assembly 7 to shrink it into the installation groove 10, and the connecting spring 9 is in a compressed state. By fitting the through hole of the upper blade body 2 with the positioning rod 6, when the upper blade body 2 is installed, the connecting spring 9 rebounds, and the positioning portion 8 abuts against the lower end of the upper blade body 2, thereby fixing the upper blade body 2 on the main blade body 1. The installation method of the lower blade body 3 is the same as that of the upper blade body 2. When the upper blade body 2 needs to be disassembled, pressure is applied to the positioning portion 8 of the positioning assembly 7 to shrink it into the installation groove 10, and the connecting spring 9 is in a compressed state, and the upper blade body 2 can be disassembled from the main blade body 1.

[0017] To elaborate further, the positioning rod 6 and the fixing part 5 are integrally formed, the positioning assembly 7 is provided in two on the positioning rod 6 and is respectively provided at the left and right ends of the positioning rod 6, and the positioning rod 6 is provided in four on the fixing part 5 and is respectively provided at the upper and lower ends of the fixing part 5.

[0018] In further detail, the connection spring 9 is connected to the positioning portion 8, and the other end is connected to the mounting groove 10 of the blade body.

[0019] Preferably, the lower blade body 3 and the upper blade body 4 are arranged as an inclined structure, which can be used for processing different positions of the product, and since both the upper blade body 2 and the lower blade body 3 are arranged as detachable structures, the utility model can be applied to the processing of different types of products.

[0020] To be more specific, the blade body 4 is fixedly mounted on the cutter body by bolts.

[0021] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0022] Although the terms such as main blade body 1, upper blade body 2, lower blade body 3, blade body 4, fixing part 5, positioning rod 6, positioning assembly 7, positioning part 8, connecting spring 9, and mounting groove 10 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
